IPNAT(8) System Manager's Manual IPNAT(8) NAME
ipnat - user interface to the NAT subsystem SYNOPSIS
ipnat [ -dhlnrsvCF ] [ -M core ] [ -N system ] -f <filename> DESCRIPTION
ipnat opens the filename given (treating "-" as stdin) and parses the file for a set of rules which are to be added or removed from the IP NAT. Each rule processed by ipnat is added to the kernels internal lists if there are no parsing problems. Rules are added to the end of the internal lists, matching the order in which they appear when given to ipnat. Note that if ipf(8) is not enabled when NAT is configured, it will be enabled automatically, as the same kernel facilities are used for NAT functionality. In addition, packet forwarding must be enabled. OPTIONS
-C delete all entries in the current NAT rule listing (NAT rules) -d Enable printing of some extra debugging information. -F delete all active entries in the current NAT translation table (currently active NAT mappings) -h Print number of hits for each MAP/Redirect filter. -l Show the list of current NAT table entry mappings. -n This flag (no-change) prevents ipf from actually making any ioctl calls or doing anything which would alter the currently running kernel. -p This flag is used with the -r flag to cause any active NAT sessions that were created by the rules being removed and that are cur- rently active to also be removed. -r Remove matching NAT rules rather than add them to the internal lists. -s Retrieve and display NAT statistics. -v Turn verbose mode on. Displays information relating to rule processing and active rules/table entries. FILES

ipnat - user interface to the NAT subsystem SYNOPSIS
ipnat [-dlhnrsvCF] -f filename The ipnat utility opens a specified file (treating - as stdin) and parses it for a set of rules that are to be added or removed from the IP NAT. If there are no parsing problems, each rule processed by ipnat is added to the kernel's internal lists. Rules are appended to the internal lists, matching the order in which they appear when given to ipnat. ipnat's use is restricted through access to /dev/ipauth, /dev/ipl, and /dev/ipstate. The default permissions of these files require ipnat to be run as root for all operations. ipnat's use is restricted through access to /dev/ipnat. The default permissions of /dev/ipnat require ipnat to be run as root for all oper- ations. The following options are supported: -C Delete all entries in the current NAT rule listing (NAT rules). -F Delete all active entries in the current NAT translation table (currently active NAT mappings). -d Turn debug mode on. Causes a hex dump of filter rules to be generated as it processes each one. -f filename Parse specified file for rules to be added or removed from the IP NAT. filename can be stdin. -h Print number of hits for each MAP/Redirect filter. -l Show the list of current NAT table entry mappings. -n Prevents ipf from doing anything, such as making ioctl calls, which might alter the currently running kernel. -s Retrieve and display NAT statistics. -r Remove matching NAT rules rather than add them to the internal lists. -v Turn verbose mode on. Displays information relating to rule processing and active rules/table entries. /dev/ipnat Link to IP Filter pseudo device. /dev/kmem Special file that provides access to virtual address space. /etc/ipf/ipnat.conf Location of ipnat startup configuration file. /usr/share/ipfilter/examples/ Contains numerous IP Filter examples.
